The rods may be secured in the channels or.A

troughs in a variety of other ways, not necessarily rigidly. For instance, annularange ef` fects Il, see Fig. 4, can'be formed on or attached to the rods, (as by upsetting, or separate washers strung on) which flange effects can readily be welded in vplace in the troughs. Thetroughs f maybe periodically embossed as at i8Figs. 7

and 8, formingcradle-like supports for the rods,

onto which thev latter can be welded. -The supports canl also be punched lout of the channel bottoms (as straps) so as to overhang the rods` to retain and/or center them assuggested in Fig. 15 atV iBa; `in which event the rods could straps, or, as suggested in Fig. 15a, bottompor-` tions lab of. the channel at each side of the hole fromwhich the strap eiect ida is punched can be bent toward thestrap to support theA rod thereagainst. The rods could be bound in place, as by staples or Wire strands i9, see Fig. 16, rpassing through the holes in the base Aportions of the y channels. i l .1

The spacing supports for the rods, such as H3,` ii, i8, etc., of the two channels Aare offset from each other so that in applying the securing meinbers inv pairs opposite each other, one or the other of such pair willwbe certain to clinchas will now be described.

The preferred fastening membersdfor the panel--M ling are horse-shoe type nails, 20, Fig-5, with special heads 2i, of suiicient widthso lthatthey will-not be likely to puncture or pull tl'irough4 the panelling which may be of relatively friablev nature. vThe nails areof nattended, rectangular crossesection, as shown in Fig. v (cf; 2li in Fig., 2), and witha very gradual taper Ato the point, for easy piercing of thepanelling and for easy bending of the points by the channels and/or rod i5 or itin. The thin `point enables relatively thin" stock to be used for the chvannels'without danger of puncturing theirwalls. The nails do not have to be flat on both sides, although this I believe is the most satisfactoryl shape. 'I'hey can beV D- shaped as shown at 202:, Fig; 2. JThe essential characteristic isV thinness invonedirection only, whereby the nails uponjencounterlng the4 deilect# ing surfaces of the ground strip, will not 'be bent in a direction longitudinally of the strip.

At the right in Fig. 3, thel nail 2E is shown with its point entering a trough at one side of a rod i5, and .at the left the nail 2U is shown in clinched positionvhaving encountered the curved wall of the trough for deflection thereby around the rod I5 as at 2i. Such clinching is eiected irrespective oi' the region in which the nail encounters the ground strip (providing this is between the two edges 9a). andl practically irrespective of the angle at which `driven through the panelling. In'being clinched, the point of the nail continues to hug the peripheral4 surface of the rod, so that a very firm anchorage is eiected between the panelling and ground strip, when the nail is completely seated. The nail should be of such proportions and length that when fully seated, it fills the space radially between the rods and channel bottoms (see Fig. 6), so that the secured panelling cannot sag or rattle. The dividing ribs I terminate in a plane below (inwardly from) the surfaces 9a of the outer walls of the strip, so that if a nail point encounters the top of the rib '1,v it will have a short portion projecting free from the panelling, and 'be more certain vto be deflected one way or the other, and finally curled around a rod. The rods are spaced Vfrom the panelling for the same reason.

If the ground strip is made of sheet-metal, this should be hard enough to prevent penetration by the nail point, lbut can be `oi' any thickness. Iii-gauge coldrolled stock is a satisfactorymaterial, as to stiiness and hardness for use asl ceiling` treatment support, as suggested inFig.1g. 7

'I'hespacing of the ground strips on the skeleton structure, such as I, is determined partly inv accordance with panel widths, so that joints ooour approximately over the dividing members 'I of the strips 5' as suggested in Fig. 3, enabling both margins.of such adjacent panels to b e rmly supported. VThe nailing can be donefromA opposite angles toward the ground strip centers in a lmapner tov d raw the adjacent edges ofthe panels, together without .affecting V`the clinching operation described.v i

Referring to the modified` ground strip shown in Fig'fl'i this illustratesthat the strip can be embedded flush with the face of concrete, plaster or' the like, indicated at`25. To holdfthe strip in place, the flanges 8 may be extended as at 26', `and, with? one or morelbends, or with ,the protuberances or 'through holes to provide` the necessary keying of the' material 25 thereto. In

use on brick or tile (see Fig. 15) the ribs 1 mayV have'throughopenings therein to receive Shanks such asi-2* of anchoring devices.' which ,may carry expanding members, suchi for example.'- .as the Vtoggle head 29 illustrated.` To receive vFig. 17 illustrates the embodiment of the es-` l sential principles of the ground strip into `a hollow stud. 4Asshown, the stud is'made from a single piece ot sheet-metal l29, with oppositely disposed trough effects `6, and rodsv i5so that Apanelling can be anchored to both sides of the stud', asin erecting partitions. The seam at30 can be closed, as by welding, or the formation of an interlocking bead,if desired, or thetwov edges can simply abut eachother.

Referring further to the panelling construction, this for supporting acoustical tile, such as shown partially at T, preferably is madeV with standardplasterboard orlath, so that paperfof the usual envelope for the' plaster core comes between adjacent plaster sheets and. assists in providing an anchorage forfastening elements, such as nails or screws. Preferably the sheets Il and l2 of the panelling slabs `are laminated in relatively offset relationship to provide ship-lap joint eiects where two slabs abut, as shown.
